Thanks JaG. I'm however not able to understand really the relation of L229 with the new SNPs and the term "chromats". I have to guess that these SNPs are all in the same region of the Y chromosome? In my case I'm tested L229- and when I ordered the new SNPs I had the L250.2+ result in only two days, but the other two are still in lab progress?

Hi Chris,

Yes, L229 is in the same segment as the new SNPs. It doesn't quite show up on the chromat posted by JaG, so let me show this view from Ymap:

A chromat is a short form of "chromatogram," I believe, a term for a lab read-out.

I don't understand why your other two orders have been delayed, that doesn't make sense to me, either.

Thanks for the list of kits, JaG. Now that's a task, for us to look them up, and write to each of them...

@JaG & Bonnie: Thanks for your explanations. So basically by testing SNPs like L229 the lab has a chromat/"chromatogram" read-out, where the result for other SNPs nearby is available. I still don't understand how long (position range) the chromat of FTDNA is: JaG has linked to 101 bp ChrY, Position 6,813,360 - 6,813,460.

About M6882 J2a3c/J2a4c (M68+): sounds very interesting. Hope I can look in detail to that later.

Thanks to you, Roy K. and Peter U. for that info. Hmm. If M68 is so widespread and downstream of L250.2/L251.2, then these two must be more widespread and older. My feeling about many J2a3* samples and also possibly other known SNPs downstream of L26 being positive for L250.2/L251.2, increases. I guess we should check every L26 subclade for M68- kits; better if we get one L250.2- for every suspicious clade. Tomorrow can bring new evidence.
